FEED-WATER HEATER AND CONDENSER.

SPECIFICATION forming part of Letters Patent No. 407,141, dated July 16, 1889.

Application filed April 10, 1889. Serial No. 306,715. (No model.)

To all whom it may concern:

Be it known that I, JOHN WILLENERINK, of New Richmond, in the county of Olermont and State of Ohio, have invented a new and Improved Feedater Heater and Condenser, of which the following is a full, clear, and exact description.

The object of the invention is to" provide a new and improved feed-water heater for steamboilers, which is very simple in construction and effective in operation, utilizing the exhaust-steam of the engine for heating the water.

The invention consists of a water-supply pipe connecting with the pump discharging into the boiler and a number of vertical pipes opening into the said water-pipe and connecting with the exhaust-pipe of the steam-engine.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a side elevation of the improvement, with parts in section.

The water-supply pipe A is provided on one end with a valve B, connected with a pipe O, leading to the tank or other source of Watersupply. On the other end of the supply-pipe A is held a second valve D, connected by a pipe E with a pump F, of any approved construction, and serving to discharge water into the boiler to be converted into steam.

From the supply-pipe A extends upward a number of pipes O, connecting at their upper ends with a horizontally-extending pipe II, closed at one end and connected at its other end by an upwardly-extending branch pipe I with the exhaust-pipe J, through which passes the exhaust from the engine. 011 the branch pipe I is held a valve K for regulating the amount of exhaust-steam admitted from the exhaust-pipe J to the pipe II. On the supply-pipe A, and on one of the vertical pipes G, is held a glass gage L, to indicate the amount of water in the pipes A and G.

The operation is as follows: \Vhen the engine is in motion, the exhaust-steam passes into the exhaust-pipe J, and part of the exhauststeam passes from the latter through the branch pipe I into the pipes II and G. Then the valves B and D are opened and the pump F is in operation, then the pump sucks the water from the tank or other water-supply so as to pass through the supply-pipes C, A, and E. As the water passes through the watersupply pipe A it comes in contact with the exhaust-steam contained in the pipes G, so that part of the exhaust-steam heats the Water in its forward motion and part of the steam mingles with the water and is carried to the pump and from the latter back to the boiler. It will be seen that when the pump is stopped and the valves 13 and D are closed the water remaining in the supply-pipesAis heated by the exhaust-steam contained in the pipes G. Then the water in the boiler sinks below its normal level, the valves B and D are opened again, the pump F is started, and the heated feed-water in the pipe A between the valves B and D is forced back to the boiler. The new supply of water passing through the pipe O and the valve B is heated again, as above described, when passing through the supplypipe A.

In case the pump F gets out of order the op erator closes the valve K, so that the exhaustair in the pipe J passes freely into the open air. The glass gage L enables the engineer to set the several valves to regulate the admission of exhaust-steam and water to the pipe A.

Thus it will be seen that I provide a very simple and convenient means for heating the feed-water from the exhaust-steam of the en- 6 Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A feed-water heater comprising a watersupply pipe connecting with the pump discharging into the boiler, and a number of vertical pipes opening into the said water-supply pipe and connecting with the exhaust-pipe of the steam-engine, substantially as shown and described.

2. A feed-water heater comprising a supply pipe having a valve near each end, a pump connected with one end of the said supplypipe and discharging into the boiler, a number of vertical pipes opening into the said water-supply pipe, and an exhaust-pipe into which discharges the exhaust-steam of the engine and which is disconnected from the said vertical pipes, substantially as shown and described.

3. In-a water-heater, the combination,with a water-supply pipe provided with valves near each end, of a number of pipes extending from the said water-supply pipe, a horizontally-extending pipe connected with the upper ends of the said number of pipes, and an exhaustpipe connected with the said horizontally-extending pipe, substantially as shown and described.

4. In a Water-heater, the combination, with awater-supply pipe provided with valves near each end, of a number of pipes extending from the said Water-supply pipe, a horizontally-extending pipe connected with the upper ends of the said number of pipes, an exhaust-pipe connected with the said horizontally-extending pipe, and a branch pipe connecting the said exhaust-pipe with the said horizontallyextending pipe, substantiallyas shown and described.

5. In a feed-water heater, the combination,- with a water-supply pipe, of a pump connected
